I have a Garmin Drive 51 and I can't get it to update the software through Garmin Express. My device is currently on software version 4.40 and the available update is 6.10, when I try to update it I get a green banner saying the update is complete but below that it tells me that I have an update (6.10) available and when I check my device info it says it is still on v4.40. Is anyone else having this problem?
